The scenario centered around a partial collapse of the Charleroi Area High School football stadium in Washington County.

"This isn't something that happens very frequently. But when it does, it's a fairly high-risk event," said Brian Kokkila, of the Peters Township Fire Department.

The drill gave rescuers practice in cutting through a large structure. There were 15 pretend victims trapped under rubble. The mannequins used to simulate the victims actually could appear to breathe and blink their eyes, showing signs of life.

The director of the Pennsylvania Emergency Management Agency said the drill is about learning about new equipment. But, Glenn Cannon also said it is about agencies learning to work together.

“You notice all the equipment that's here,” he said. “There are literally millions of dollars worth of equipment that is sitting here that has been purchased over the last 10 years to be able to equip and train these crews for this type of operation.”

Jeffrey Yates from Washington County Public Safety said the training helps educate rescuers on, “cutting concrete, cutting metal, rescue from heights, just a lot of the difficult rescues that require specialized training and specialized equipment.”
